Something new to worry about

We already knew that sitting too long in front of a computer could give you a backache, neckache, headache, blurry vision, and seriously annoyed family members. But who knew it could give you a blood clot, too? The condition, nicknamed "economy class syndrome" as it was previously mostly seen in people who spent too much time in cramped airplane seats, is brought on by going for long hours without standing up; a blood clot forms in those idle legs and travels to the lungs. And if I read anymore about this, I shall become convinced that such a thing is happening to me right at this very moment. Time to take a walk!
